Final answer:
The net amount of water benefiting the crop when a pump delivers a gross flow rate of 2.4 CFS to a 12 acre field for 10 hours with an irrigation efficiency of 73% is 63,072 cubic feet.
Step-by-step explanation:
You want to know the net amount of water benefiting the crop when a pump delivers a gross flow rate of 2.4 Cubic Feet per Second (CFS) to a 12 acre field for 10 hours, with an irrigation efficiency of 73%. First, let's calculate the total amount of water delivered:
Convert the flow rate to Cubic Feet per Hour (CFH): 2.4 CFS * 60 minutes * 60 seconds = 8,640 CFH.
Multiply by the total hours: 8,640 CFH * 10 hours = 86,400 cubic feet.
Now, let's calculate the net amount of water using the efficiency:
The net amount is 73% of the total delivered: 73% of 86,400 cubic feet = 0.73 * 86,400 cubic feet.
Calculate the net amount: 86,400 cubic feet * 0.73 = 63,072 cubic feet.
Therefore, the net amount of water benefiting the crop is 63,072 cubic feet.
